我如何將字符串從另一個文本文件（逐行讀取）放入數組中，但只讀取每隔一行

Question

（在 txt 文件中）

line

line

notice that there's a blank line between line

我希望數組看起來像：x = [“line”，“line”，“注意行之間有一個空行”]

Answer 1

嘗試

txtFile = open("yourfile.txt").readlines()
x = [txtFile[i].strip() for i in range(len(txtFile)) if i % 2 == 0 ]

編輯：如果您只想刪除空白行，請嘗試將 x 變量行替換為

x = [txtFile[i] for i in range(len(txtFile)) if txtFile[i] != "\n"]

Answer 2

你可以這樣做 -

with open("file_name.txt") as file:
    result = [line.rstrip() for line in file if line.rstrip()]
    print (result)

O/P: ['line', 'line', "notice that there's a blank line between line"]
